7.10 External analog inputs
The external analog inputs are analog signals that are transferred to the device via an interface from ex-
ternal systems. The external analog inputs can also be written by a barcode scanner (see
chapter 11.4.2 "Texts and process values", Page 276).
The external analog inputs are pooled into groups along with other analog signals via the "Groups" con-
figuration and are then available for further use via these groups.

Temperature The parameter determines whether the transferred value (measured value) is eval-
uated as a temperature value, a temperature difference, or not as a temperature.
The distinction between temperature value and temperature difference is significant
for conversion from °C to °F.
None The value is not a temperature.
Temperature difference The value is a temperature difference.
Temperature value The value is a temperature value.
